Our second character art reveal for The Mark of Athena is Nemesis, goddess of revenge. What's her role in the book? No spoilers, but here's a little information:

NemesisAlso known as the goddess of revenge. This is one
lady you do NOT want to run into in a dark alley (or anywhere else, for that
matter).What does SHE do? This woman can
shape-shift into any imposing figure you can imagine, if you’re her target.
Which you don’t want to be. Ever.Noteworthy: Imposing as she is, Nemesis can
be bargained with, as demigod Leo will learn…but at what cost?
